SHUTTER-WORKER.

LLkmelE-ICATION forming part of Letters Patent No. 318,421, dated lVIay19, 1885.

(No model.)

To aZZ whom it may concern.-

Be it known that I, RUssnLL G. DUDLEY, a citizen of the United States ofAmerica, residing at Jersey City, in the county of Hudson and State ofNew Jersey, have invented certain new and useful Improvements inShutter-Operators, of which the following is a specification, referencebeing had therein to the accompanying drawings.

This invention relates to that class of shutter-operators in which theturning of a handle inside the house operates two bevelgears, one ofwhich is on a shaft that carries an arm connected to the shutter to beoperated on; and the invention consists in the peculiar combinations andthe construction and arrangement of parts hereinafter described andclaimed.

In the accompanying drawings, Figure 1 represents a side elevation withthe casing broken away to show the interior construction. Fig. 2 is ahorizontal central section of the case. Figs. 3 and 1 are elevations ofthe locking device in two positions.

leferring now to the details of the drawings, A. represents a spindle,preferably square in cross-section, provided with a handle, B, at oneend, having a correspondinglyshaped orifice, and having its other endfitted to a similar orifice in the hub O of a bevelwheel, D, having itsbearing in a casing, E, and meshing with another bevel-wheel, F, on anupright shaft, G, journaled in bearings formed in the casing E, andcarrying an arm, H, having a pin, l, with which connections maybe madewith the shutter in any manner desired.

The casing consists of a box-like main part, E, provided with ears 0,having holes (shown in dotted lines) for securing it to the window, andprovided with a cap, J, having extensions j (at top and bottom) fittinginto recesses or deep notches formed in the top and bottom of thecasing, and ears by means of which the cap and easing are joinedtogether by pins 7; 7:, which pass through from side to side of thecasing, and are riveted therein or otherwise secured. I have shown twopins k, but it is evident that only one could be used, if preferred.

The casing E has one half of the bearing for the shaft G formed in it,and the other half is formed by the extensions 7', so that when the capis fastened to the casing the shaft G is securely fastened in its place.

At 0 is shown a slot through which the gears can be seen, so that it canbe readily discovered whether the gears are properly fitted togetherwhen the parts are assenr bled. This hole being at the back of thecasing is closed by the woodwork of the win (low-frame when the casingis in use, and as the outer part of the casing is closely stopped thereis no danger of the operating parts be ing frozen together by watergetting to the gears and freezing them fast to each other. Thisconstruction of the casing not only admits of keeping out the water,&e., but admits of the ready assembling of the parts, as it is onlynecessary to set the hub of the wheel D into the hole made therefor inthe casing, then drop the shaft Gin its place, set on the cap J, andfasten the whole together by the insertion of a pin, 71/, or pins h 71,as the case may be. It will thus be seen that the wheel F holds thewheel D in place, and that the shaft G is held in place by the cap. Nearthe handle is shown a combined escutcheon and lock consisting of theplate L, having a fixed clamping-jaw, Z, a moving clampingjaw, M,pivoted to the plate, and an eccentric lever, N, piv'oted between ears Zon the plate L. This clamp surrounds the spindle between the handle Band a collar, 0, on said spindle, by means of which the latter is firmlysecured in place when the plate is secured to the window-easing.

When the shutter-operator is in use, it is only necessary to turn thehandle to adjust the shutter in any desired position, and then byturning the eccentric lever N the clamping-jaw M is pressed down fast onthe spindle, holding the latter fast, and thus securely fastening theshutter in any desired po sition. 9 5

It will thus be seen that by this construction and arrangement of partsa cheap yet strong shutter-operator is made, that will neither get outof order nor be frozen fast, and one with which the shutter can bereadil y adjusted to any desired position from wide open to close shut,and then looked fast in such position.

\Vhat I claim as new is 1. In a shutter-worker, the casing E and thebevel-gear D, having a hub fitting into abearing on one side of saidcasing only, and held in'position by the bevel-gear F, in combinationwith the Vertical shaft G, carrying said bevel-gear F, and the arm H,for operating the shutter, substantially as described.

2. The combination, with the spindle of a shutter operator, of thepivoted jaws Z M and the eccentric lever N, substantially as described.
